Mobility Measurements Probe Conformational Changes in Membrane Proteins due to Tension

, 2015
The function of membrane-embedded proteins such as ion channels depends crucially on their conformation. We demonstrate how conformational changes in asymmetric membrane proteins may be inferred from measurements of their diffusion.

Estimating prognosis in patients with acute myocardial infarction using personalized computational heart models [PDF]

, 2017
Biomechanical computational models have potential prognostic utility in patients after an acute ST-segment–elevation myocardial infarction (STEMI). In a proof-of-concept study, we defined two groups (1) an acute STEMI group (n = 6, 83% male, age 54 ± 12 ...

A method for using surface tension to determine the size of holes in hardware [PDF]

, 1969
To check the size of small holes in injectors, flow control orifices, filters, and similar hardware, a surface tension technique is used. The liquid surface tension causes it to act as a membrane when pressure is applied.
